Patient and visitor hand hygiene has the potential to prevent health care-associated infections, but there are few data on the efficacy of interventions to improve patient/visitor hand hygiene.
To determine whether conventional and front-line ownership (FLO) patient/visitor hand hygiene interventions improve patient/visitor and health care worker (HCW) hand hygiene rates.
A stepped wedge cluster randomized controlled trial was conducted on inpatient units and the emergency department. A conventional intervention included pediatric-focused posters, which also served as reminders for HCWs. This was compared to a FLO intervention aimed at finding "positive deviants," staff who were already taking steps to improve patient/visitor hand hygiene. Patient/visitor and HCW hand hygiene rates were measured covertly by trained medical students.
Patient/visitor hand hygiene rates increased from 9.2% at baseline to 13.9% in the post-intervention period. Hand hygiene rates on units randomized to the standard intervention changed from 7.3% to 10.9% (P = .46), but FLO intervention units significantly changed from 14.3% to 25% (P = .03). The baseline HCW hand hygiene rate was 68.2%, which increased to a greater extent in the FLO group (79.1%) than in the standard intervention (73.1%), but the change was not statistically significant for either intervention compared to control (P = .18 and P = .64, respectively).
Hand hygiene interventions in hospitals can improve patient/visitor and HCW hand hygiene rates, and a FLO intervention appears to be more effective than a conventional intervention.
患者和访客手部卫生有可能预防医源性感染,但关于改善患者/访客手部卫生的干预措施效果的数据很少。
确定常规和一线人员(FLO)患者/访客手部卫生干预措施是否能提高患者/访客和医护人员(HCW)的手部卫生率。
采用阶梯式楔形集群随机对照试验,在住院病房和急诊部门进行。常规干预措施包括以儿科为重点的海报,这些海报也提醒了 HCW。将其与 FLO 干预措施进行比较,FLO 干预措施旨在寻找“积极的偏差者”,即已经采取措施改善患者/访客手部卫生的员工。受过培训的医学生秘密测量患者/访客和 HCW 的手部卫生率。
患者/访客的手部卫生率从基线时的 9.2%上升到干预后的 13.9%。随机分配到标准干预组的病房的手部卫生率从 7.3%上升到 10.9%(P=0.46),但 FLO 干预组的手部卫生率从 14.3%显著上升到 25%(P=0.03)。基线时 HCW 的手部卫生率为 68.2%,FLO 组的手部卫生率上升幅度更大(79.1%),而标准干预组的上升幅度较小(73.1%),但这两种干预措施与对照组相比均无统计学意义(P=0.18 和 P=0.64)。
医院的手部卫生干预措施可以提高患者/访客和 HCW 的手部卫生率,FLO 干预措施似乎比常规干预措施更有效。
